HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 610, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 985, 610, 438 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 985, 610, 438 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 985, 610, 438 is 1.

HCF(985, 610, 438) = 1

Highest Common Factor of 985,610,438 using Euclid's algorithm

Highest Common Factor of 985,610,438 is 1

Step 1: Since 985 > 610, we apply the division lemma to 985 and 610, to get

985 = 610 x 1 + 375

Step 2: Since the reminder 610 ≠ 0, we apply division lemma to 375 and 610, to get

610 = 375 x 1 + 235

Step 3: We consider the new divisor 375 and the new remainder 235, and apply the division lemma to get

375 = 235 x 1 + 140

We consider the new divisor 235 and the new remainder 140,and apply the division lemma to get

235 = 140 x 1 + 95

We consider the new divisor 140 and the new remainder 95,and apply the division lemma to get

140 = 95 x 1 + 45

We consider the new divisor 95 and the new remainder 45,and apply the division lemma to get

95 = 45 x 2 + 5

We consider the new divisor 45 and the new remainder 5,and apply the division lemma to get

45 = 5 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 985 and 610 is 5

Notice that 5 = HCF(45,5) = HCF(95,45) = HCF(140,95) = HCF(235,140) = HCF(375,235) = HCF(610,375) = HCF(985,610) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 438 > 5, we apply the division lemma to 438 and 5, to get

438 = 5 x 87 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 438 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(438,5) .
